Had the car on a dyno!

On this safe setup of low revs, and low boost / fuel it still made 362bhp / 378ft lb! 305whp.

I think she will stay at this power until i sort the brakes / suspension.

200bhp down?

That's a bit rubbish?

At 305 whp its actually 257 down at the wheels. As i said i could turn it back up but would rather sort other stuff first.... its still incredibly fun at this level - and thats what i want

I guess as well considering you paid for new engine the costs must be adding up and having another broken engine would be a big risk.

Definitely a marmite car.

As we found out the engine wont cope at max power for eternity. But there is still scope for forging to produce some stupid numbers.

But as i said, for now 362 is 'nice'

The nice thing is engines are cheap. Cheaper than fixing them anyway 😂

Had a nice weekend at Modified Nationals!

Entrance photos

The blue rope was attached to a kit car that i towed in. But a bit of boost in 2nd snapped the rope lol.

Have you got any performance figures for it ?

How would it compare to say a C63 or similar over a 1/4 mile ? is it a case of quick once its rolling, I imagine getting it off the line could be challenging

I havent yet.

Needs a few more tweeks before i up the power and get some figures sorted

[Palmers]

Its a caddy guys, thats why...

And for the people going on about the smoke: I clearly always drive it at maximum throttle lol

The Spruce goose said:

I notice it is for sale on ebay, you just fancy a change?

Not really i want to keep it. But needs must.

Deffo be having one again

[Palmers]

Nothings been really happening. Ive been driving the car regularly.

Yes, it is advertised for sale, priorities and all that. But id rather keep it in all honesty. Id deffo have one again so it seems a bit daft to get rid now - it was my childhood dream!

The car has started to feel a bit wandery up the front end, hardly suprised considering all the suspension is standard.

So its coming off the road over winter for a few tweeks to be made, dependant on how funds allow. Its going to be a long project...

Have you got 1/4 mile times yet?

No its been no way near a drag strip or track. Probably wont for a few years lol

When you stripped the failed engine did you notice evidence of bore score on all cylinders? I imagine bore wash would be a major concern on this car.

Also, given the amount of fuel you're chucking into the cylinders, do you get oil dilution? Imagine the smoke you'd see when this thing runs away!

I didnt take the failed engine apart. Looked down the intake and could see the piston in the valves!

Never heard of bore wash being an issue on these, or had an issue with dilution.

These dieselmeken pumps have never had a runaway, but with the lift pump id just turn the car off, soon run out of diesel lol

Diesel runaway is when they start burning their sump oil. Turning off the fuel won't help.

I have no idea what i was on about then.

But yeah, 6th gear dump clutch.

If that fails put your head between your legs and kiss your valves goodbye (again) hahah!

[Palmers]

Car has come off the road for winter and some needed upgrades. Ill update as i go on here. Let the fun commence!

For the love of all that's holy, please put OEM bumpers on, those look like cheap aftermarket things like you'd find advertised in the back of Max Power mag...

The rear is standard, the front is an AMG.

And i will put on my car, what i like, thanks.

Full amg kit will be going in the future.

Considered going with a variable geometry turbo (or two)?
Would make the boost curve less spiky.
And water injection so you don't need to run it so rich.
Water is cheaper than fuel

First on the list is a twin scroll quick spool manifold - for obvious reasons lol

J4CKO said:

Fair enough, think it needs the rest of the kit to balance it out, the front one perhaps looks a bit out of place with the rest of the car being standard, think the rest of the AMG kit will balance it out and make it look more factory/OEM.

I dont like the rear or side at the moment. Needs the rest of the kit to finish it off. And then hide that ugly exhaust with a pointy down tip.
